The construction of Paide order castle was started in 1265 under the leadership of Konrad von Mandern. The original tower of Tall Hermann was octagonal with the height of over 30 meters and the thickness of the walls of about 3 meters.
At the beginning of the Livonian War the Russians repeatedly besieged Paide, but only in 1573 they finally managed to invade Paide. After that it changed hands several times until the Swedes got it in 1608. In 1638 they removed Paide from the list of castles.
The rampart tower and castle ruins were first conserved at the end of 19th century. In 1913 a park was planted on the hill. In 1941 Soviet soldiers destroyed the rampart tower, the symbol of both Paide and Järva County. To celebrate the 650th anniversary of the St. George's Night uprising the tower was restored in 1993. Today it houses a museum.

The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
